Interesting.  I bought a similar thing for £5 in a charity sale.  Digikam not 
only could handle the pictures, but it told me the model of the camera.  My 
guess is that .ppm extension causes the problem.  It's odds-on that the camera 
isn't actually using portable-pixmap format.  Can you not drag the files onto 
your hard drive from a file manager, then experiment with changing the 
extensions?  That's what I'd try, anyway :-)

It's academic, of course.  No-one would seriously suggest that programmers 
should waste their time trying to support cameras like this, but I hate to be 
beaten, and am determined to find a solution if one exists :-)

New to KDE4? - get help from http://userbase.kde.org
Just found a cool new feature?  Add it to UserBase
